To allwh'omz't'may comm-1b.,

Be it known that I, CHARLns 'H. Arrs, of East Orange, in the county of Essex and State of New Jersey, have invente'd'a certain new and useful Improvement in Water Gauges, of which improvement the following is a specification. y

My invention relates to water gauges for steam boilers, of what is known as the reflex type, and its object is to present a gauge of such type which shall be of sum ple and compact construction, embody a minimum number of parts, occupy small space on the boiler, and be adapted for the reception of one or more reflex glasses, to make possible observation of water level in the boiler from different, angles.

The improvement claimed is hereinafter partly in section, of a water gauge embodymg my invention; Fig. 2, a side view, in elevation, of the body of the gauge; Fig. 3, a plan or top view; Fig. 4, a bottom view; Fig. 5, a transverse section through a double glass gauge; Fig. 6, a similar section through a single glass gauge; Fig. 7, a vertical section through the upper portion of the gauge, showing a detachable stem; and, Fig. 8, a similar section through the lower portion of the body, without a connected stem.

In the practice of my invention, I provide a body, 1, which is of strong metal, as bronze, and is of polygonal (in this instance quadrangular) transverse Section, and tapered, or of contlnuously mcreasing transverse section, from its upper to its lower end. The body, 1, is fitted in a correspondingly tapered metal case, 2, and is provided, at top, with a tubular stem, 1 which, as

shown in Figs. 1 and 2-, is formed integral with it, and, in Fig. is. separate and detachably connected to it. The body and case are drawn, and firmly held together, bya" nut, 3, engaging the stem, 1 of the body,

and bearing, through a washer, 3*, on the case being parallel and in line vertically one With the other. Lips, 2,are formed on body.

the opposite sides of each 'of the slots, '2",

of the-casing, said lips: forming shoulders against which, and betweenthem and the sides of the adjoining slot, 1, in the body, i

a strong plate of glass,4, is fitted. Gaskets,

which it abuts, and when, the body, is drawn 3, asteam'and Water tight joint is formed 5, are interposed between the glass, and the surfaces of the'casing, and of theibody, onv

between the glass and the enclosing case,

by the wedging action exerted upon the glass, in two convergent directions,by the HA shown in Figs. land 2, a tubular stem,

1, which communicates with ,the interior of the body, is formed on'the-bottomthere of, said stem "being adapted for connection to a pipe leading to the water spaceof the boiler, and controlled b-ya cook or valve. The upper tubular stem, 1*, is similarly adapted for connection to a pipe leading to the steam space of the boiler and controlled by a coclror valve, and the interior of the body, 1, being thus in communication with the steam and water spaces, respectively, v H of the boiler, the level of water therein will correspond with that of the water in the boiler and will rise and fall correspondingly therewith; As shown in Fig. 8, the body is not provided with a lower stem, the pipe communicating with the boiler being, in this case, connected. directly to. the body.

As most clearly shown in Fig. 5, in the water gauge above described, two glasses, 4, are applled, but a greater or less number may be adopted in the discretion ofthe constructor, without departure from the r spirit of my invention. Thus',as shown in Fig. 6, the body may haveonly a single slot, between which slotand'the slot of the case, a single glass, 4, is interposed and tight tion first described.

The leading and characteristic structural joints formed between it and the body and case, in the same manner as in the construe 100 signs, prior in the art, so far as my knowledge and information extend,"consists in the means, substantially as hereinbefore de scrlbed, whereby wedging'action, which effects the sealing of the joints between the case and the glass, or glasses, fitted therein, is exerted, in two convergent directions, by

the direct action of a body, which is longitudinally tapesed on more than one of its sides, upon case Within which it is fitted, and which is correspondingly tapered.

I claim as my invention and desire to secure by Letters Patent:

1. n a. water gauge, the combination of a body, which is longitudinally tapered on more than one of its sides; a correspondingly tapered case surrounding said body, one or more glasses interposed between the the body and case, and means for effecting a steam tight joint between said glasses and the ease, by the exertion of wedging action, in two convergent directions, on the glass or I i 2. in a Water gauge, the combination of a body, which longitudinally tapered on more than one of its sides, a corresponding- 1y tapered case surrounding; said body, one

1 more interposed between the body and case, and means for drawing the case to a tight bearing on the glass or glasses.

3. In a water gauge, the combination of a body, which is longitudinally tapered on more than one of its sides, a correspondingiy tapered case surrounding said body, one or more glasses interposed between the body masses and case, and a nut bearing on the case and engaging a screw on the body.

4. in a water gauge, the combination of a body, which is longitudinally tapered on more than one of its sides; a correspondingly tapered case surrounding said body, one or more glasses interposed between the body and the case, gaskets fitted between the glasses and the case, and means for tight ening the case on said gaskets, by the exertion of Wedging action, in two convergent directions, on the glass or glasses. 7

In a water gauge the combination of: a body, which is longitudinally tapered on more than one of its sides; tubular stems;

connected. to opposite ends thereof, a correspondingly tapered c; .;e, on which the body bears directly thIOb, went; one or more glasses interposed between the body and case, and means for eFecting-a steam tight joint between said glasses and the case, by the exertion of wedging action, in two convergent directions, on the glass or glasses.
